COMBINED WAGON AND AUTOIIIOBILE DUMP.

Application led July 16,

To all whom t may concern: l

Be it known that we, FRANK J. Lunel-r and WILLIAM H. MYERS, citizens of the United States, and residents, respectively, of Ottawa, in the county of La Salle and State of Illinois, and Utica, in the county of La Salle and State of Illinois, have invented a new and Improved Combined -Wagon and Automobile Dump, of which thefollowing is a description. l

. Uur invention relates to vehicle dumps of the type in which the wheel supports for the vehicle areadapted to assume a position for tilting the vehicle bodilyand in which provision is made for receiving and dumping either a wagon, or an automobile truck.`

The present invention is 'designed as an improvement on the invention forming the subject matter of an application liiled by' us July 11, 1919, Serial Number310,273, and is characterized by a novel forni andarrangement of the means for controlling the tiltable elements provided for dumping an automobile'or those tilting elements provided for dumping a wagon, the invention including a different arrangement of the levers involved in the control means as well as a novel brake, and by a novel relationI of the brakes to the latch-releasing levers.

The invention is furthermore characterized also by a novel arrangement of choclrs J and controlling means therefor. Other distinctive features will the description proceeds.,

Reference is to be had tothe accompanying drawings forming a part of this specilication, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 9 is a similar view with only the wagon dump in tilted position for the dumping o f the wagon.

Incarrying out our invention in accordance with the illustrated example a suitable fixed frame 10 is provided, the frame being here shown as supported on legsll, On the frame fixed platform sections-12 and 13'are provided at the front and rear ends respectively on which vehicles mayroll/to and from the dumping elements. v y

A dum'ping platform 14 isprovided presenting side stringersll within fixed stringer-lilre sides of frame 10 and mounted to tilt with the transverse shaft or rodI 16 as a center. Latch means is provided at the rear end of the platform 14-'to 'hold the same in the raised position at a levelwith the roadway. Said latoh means is in the form of a transverse rock shaft17 turning in hanger bearings 18 or their equivalent on the frame 10, said shaft being' offset or of cranked form at the center andA for its major portion so as to swing beneath o r away from the ad- 'acent rear end of the platform 14. One'end of the shaft 17 is provided with a lever handle 33 hereinafter referred to for turning it to and from-the'latching position. In the latching position the shaft 17 engages in gains or rabbets 21 formed in the ends of the stringers 15 which are faced at said rabbets with metal straps 2() to take the wear. lhen an automobile truck or the like isdriven on the platform 14 and the-latch 17 is released, the rear end of said platform will drop to tilt the automobile toy permit the contents to readily flow therefroi'n.-.

The tilting movementl of platform 14 in the present example'of our invention is checked by a spring 22 secured at one end to said platform and connected by a short cord-22a or equivalent means with a fixed part of the structure.' The tilting vmovementfinally is arrested by the lateral bent ends '22" 4of hangers 22u obliquely disposed atA the under side of the fixed structure. The' movement of theplatform 14 to the dumping positionl is controlled in the illustrated form of our invention as follows: A depending bar-23 is pivotally secured at its upper end to said platform adjacent to the forward end. From its pivotal point said bar 23v extends downl' The brake shoe 25 is pivotally secured between its ends as at 28a to a bracket 28 Aon a brake beam 29 `supported in keepers 30` on the under side of the fixed structure, one end of the brake beam being fulcrumed lin any suitable manner as by an angle bracket 31 thereon through which the adjacent end of the hinge pintle 27 loosely extends. The other end of brake beam 29 is secured to a brake rod 32 extending ylongitudinally of the structure7 the Wjaosite end ofvsaid rod being connected to a. handy lever `33 on latch shaft l17 so that one and the saine lever operates the latch shaft 17 and controls the brake beam 29.

rlhe fixed platform section 13 has an opening therein covered by a hinged board 34` adapted to be raised, for .permitting the contents of the automobile truck to be discharged into the pit whichl extends beneath the rear end of theframe.y .y 4 v The wheels of the'V automobile and. the wagon wheels as well when arriving at the platform 14 run on stringers 35 which are rockable on short shafts 16a so as to drop to a tilteddumping position, and means is provided to sustain the stringers 35 in fixed relation to the platform 14 except when it is desired to dump a wagon. The rear ends of the stringers 35. are adapted to be engaged by the oHset or cranked portions 36 of a transverse latch shaft 37 which is rockable to throwfits cranked or latching portions 36 intoy or out of engagement with theadjaeent ends of thestringers.

The dumping movement ofthe stringers 35 is controlled by brakey means 'corresponding with brake means for the platform 14, there being a depending member 23 pivotally hung at its upper end'on transverse latform section 35a connecting the stringers.

35 atthe front ends. The` depending member 23a extends between a brake lblock 24a and brake shoe 25a. lmounted in a manner described with respect to block' 24 andy yshoe 25, the brake. beam 292L .to which the shoe 25a is pivotally secured,A being connected at one end with a brake rod 32a, the

opposite end of which is secured to an arm 37a on the latch shaft 37 provided with an operating lever 33, so that the same lever33a operates said latchshaft and controls the brake beam 29a. They latch shaft 37 turns in a suitable bearing 38 on the platform 14 and intermediate bearings 39 of longitudinal beams `14EL `of said platform. The lever 33a extends upwardly vthrough a' slot 40 in the adjacent side of the fixed structure 10 so that it and the shaft 37 may riseand fall with the tilting of the platform 14 but said shaft 37 1 will remain stationary with the platfrom 14 when the stringers 35 are tilted to dumping position.

We provide a pair of chocks or wheel blocks`41 on stringers 35 and a second pair of chocks or wheels blocks 42 on said stringers and distant from the first blocks, so that vehicles of different lengths of wheel vbase may be chocked. The chocks 41 are hingedly secured at one end as at 43 to swing upwardly at an angle tothe stringers to thereby offer an obstruction or to be lowered onto the stringers. Levers 44 are fulcr'umed as at 45 at the under side of the frame 10 and the upper ends 46 thereof-arey disposed adjacent to the underside ofl chocks 41. The short arms 47 of levers 44 `have connected therewith retractile springs 48, the opposite ends of the springsbeing secured as at 49 to the stringers 35. vTo each chock 41 are secured the upper ends of guidearods 5() which extend freely through brackets 5l on stringers 35.'v The springs 4S. normally tend to maintain the chocks 41 raised so that the wheels of a vehicle backing onto the` dump move rearwardly along the stringers 35 and will be engaged by the chocks 41.

The vehicle moving in the opposite direction e 1 will automatically depress the chocks 41 'and` after the wheels pass the chocks the. latter will automatically rise under the action of the springs 48.

The additional chocks 52V ico normally tend to lie flat on the stringers 35 under their own gravityi said chocks having guide rods 53 pivotally connected;therewith7 saidguide rods passing through .brackets 54 on the stringers.` The stringers 35 have cutouts or recesses 35b for the guide rods 50, 53,l

to lie within the planes of theadjacent sides of the stringers. lThe levers 55 are fulcrumed as at 56 to the stringers 35 andv extend upwardly through the stringers. so that their upper ends lie adjacent to chocks 52. The short arms ofthe levers 55 have eyes 56, 57 or equivalent means to which one end of an operating cord 58 is'secured. The

cords 58 Afrom the respective levers 54 pass through suitable guides 59 and are secured position as indicated in Fig. 47 the platform 14 remaining in the raised position.. In the movement to the inclined position the stringers 35 are controlled by the lever 60 which is initially thrown to a position to 1,429,899 ggg' release the stringers and given a continued movement to act on the brake lever 28a through connecting rod 32a.

In dumping grain from a Wagon the grain drops through an opening covered by a hinged door 61 which door is raised for the purpose. When an automobile truck is to be dumped if it is backed onto the stringers 35, the Wheels Will be engaged by the chocks 41 or if the automobile is driven forwardly the Wheels will automatically depress said chocks until they have automatically passed over the same when the chocks Will automatically rise. For the dumping of the automobile, the stringers 35 are maintained held by their latch shaft 37 and the lever 33 is thrown to so rock the latch shaft 17 as to release the rear end of the platform 14, the brake having been applied With the throwing of the lever, so that the combined dump may assume a tilted position, shown in Figure 3, the stringers 35 being constrained to remain in the plane of the platform 14.

ln order to prevent the operation of the latch means and the release of the dumping platform 14 before the door 34 is raised, and otherwise to prevent the accidental tilting of the platform, We provide for controlling the latch means by said door for which purpose, We provide, (see Figures 2 and 7), an arm 62 on the latch shaft 17 and extending adjacent to the plane of the door 34, said door having a cleat 63 thereon at the under side or equivalent means to engage the arm 62 When the shaft 17 is in the latching position engaging the stringere 15. Thus, the latch shaft cannot be rocked to release the platformy until the door 34 is raised. Similarly, the latch shaft 37 has an arm 64 thereon extending adjacent to the plane of the door-61 and said door has a cleat 65 thereon to engage said arm when said door is in the closed position.

We would state in conclusion that While the illustrated example constitutes a practical embodiment of our invention, We do not limit ourselves strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied Without departure from the spirit of the invention as defined in the appended claims.

Having thus described our invention, We claim:
